Ok, some background - DS is currently four months old, is FF and a good sleeper. I know he can settle without me as DH often takes over so I can have a night off. PIL have been fantastic, esp MIL (who I feel lucky to have after reading some of the MIL threads on here!). They have looked after DS a couple of times in the day/evening for us and have been fine.
DH and I are going to a wedding next month and PIL are having him for the day/eve - MIL has asked if she can take him to a BBQ and I'm fine with that - he has been further in the car already and she will have the car seat. I know I can trust her completely to feed him at correct(ish!) times, keep him in the shade etc. Yesterday FIL asked if they can keep him overnight that day. I told FIl I didn't see a problem but I'd have to play it by ear - if he starts waking up in the night again or is teething etc it might not be wise. DH is all for it as it means we don't have to rush back from the wedding but I'm a bit unsure. Common sense tells me there's no reason he can't stay with them - we have a little steriliser they can borrow, we can easily get a travel cot before then, and like I say I trust them to look after him properly. But I'm not sure I want my baby away from me for that long! By the time we pick him up it will have been over 24 hours apart. Before people ask, I would feel exactly the same if it were my parents asking.
I would really like to know what people think - I really don't know if I'm being a bit PFB or if everyone would feel that same!
